MACHINE FOR SLOTTING UMBRELLA-=STICKS.

SPECIFICATION forming part of Letters Patent No. 391,648, dated October 23. 1888.

Application filed May 17, 1888. Serial No. 274,159. (No model.)

To aZZ whom it may concern.-

Be it known that 1', JOHN B08118. citizen of the United States, and a resident of Philadeh phia, Pennsylvania, have invented certain Improvements in Machines for SlottingUmbrella- Sticks, of which the following is a specification.

The object of my invention is to provide a machine for rapidly slotting or slotting and to drilling the sticks of umbrellas or parasols for the reception of the runncr-retainers, the machine being such that no preliminary marking of the stick is necessary in order to determine the proper location of the slot or mortise therein, so that the expense of this preliminary marking is saved.

In the accompanying drawings, Figure 1 is a perspective view of an umbrellastick slotting and drilling machine constructed in accordance with my invention. Fig. 2 is a transverse section of the same on the linel 2,and on a larger scale. Fig. 3 is a detached perspective view of part of the machine, and Fig. 4 is a diagram illustrating a modification.

On a suitable work table or bench (illustrated by dotted lines in Fig. 1) is mounted a head, A, having suitable bearings for the shaft or mandrel of a saw, B, which is secured to that portion of the mandrel projecting beyond the head A, so that it can be readily applied to or removed from the same, that portion of the mandrel beyond the saw forming or being provided with a split chuck, a, for holding a drill, D, as shown in Figs. 1 and 2.

In a box, I), in front of the head A, is guided vertically a slide, F, which has at the upper end a head, F, on the top of which are lugs or projections d, with V-sh aped notches, as shown in Fig. 3. The head F has also a transverse opening for the reception of a rod, G, which can be adjusted laterally in said head and secured in position after adjustment by means of a set-screw, f. This rod carries two gageblocks, J J, also provided with notched lugs or 5 projections g, and each adjustable on the rod G, and capable of being secured in position after adjustment by means of a set-screw, h.

To the lower end of the slide F is pivoted a rod, K, connected at its lower end to a treadle,

5o M,which is hung to a suitable foot or standard, i, secured to the floor beneath the work bench or table, and from the front of the slide F projects a lug, k, carrying a set-screw, m, with a lock-nut, m, this set-screw working in connection with a stop, a, on the face of the box Z in which the slide F is guided.

In preparing the machine for operation the rod G is so adjusted in the head F and the gages J J are so adjusted upon the rod that when the shoulder formed by the handle of the stick is pressed against the lug of the gage J that portion of the stick in which the slot for the lower runner-retainer is to be formed will be directly beneath the center of the saw B,while, if the stick is reversed and the shoul- 6 der formed by the handle is pressed against the lugg of the gage-block J, the center of the saw will be directly over that portion of the stick in which the slot for the upper runner-retainer is to be formed. The stick being placed on the gages in the position shown in Fig. 1, pressure is exerted upon the treadle M, so as to cause the rise of the slide F and the carrying of the stick up to the saw, the depth of kerf formed in the stick being determined by the contact of the set-screw m with the stop a. The slide is then lowered, the stick reversed, and the slide again raised, so as to form the slot for the upper retainer therein.

The notched lugs d on the head of the slide serve to support the stick at points close up to the saw, so as to effectually prevent any springing of the stick, such as would interfere with the proper formation of the kerf therein or would cause variation in the depth of the kerf.

The drill D at the end of the saw-mandrel provides a ready means of forming in the stick a transverse opening for the reception of a pin, if such pin is employed for the purpose go of securing the retainer in the stick.

It will be observed that no marking of the stick is necessary in order to indicate where the slots are to be formed therein, nor is any special care or skill required in adjusting the 9 5 stick, so that the slotting of the stick can be effected very rapidly and by the employment of cheap or unskilled labor thus removing an item of considerable expense in the present method of slotting the sticks for the reception of the retainers.

In carrying out my invention it is notabso lutely necessary that two gages, J J, should be employed upon the rod G, as but one gage, J, might be used, a number of sticks having the lower slots formed therein, and the rod G being then adjusted in the head, so that the gage J will be properly set for the formation of the upper slots in the sticks, or the rod G may, if desired, be fixed and the gages adjustable thereon; and in some cases the saw may be movable instead of the stick-support, such a device being shown in Fig. 4, in which the saw-mandrel is carried by a pivoted frame, A, connected to the slide F, the stick-support F forming part of the fixed head, which also carries the set-screw m, the slide F having the stop at.

Drills, inortising-chisels, or other tools may also be used in place of the saw, if desired,

forming a stop for a shoulder on the stick, whereby the longitudinal position of the stick in respect to the tool is determined, all substantially as specified.

2. The combination of the cutter, the stickcarrier, av device for moving one of said parts from and toward the other, and gages located on opposite sides of the axis of the cutter, said gages serving as supports for the stick and forming stops for engagement with a shoulder on the stick, all substantially as specified.

3. The combination of the cutter, the stickcarrier, a device for moving one of said parts from and toward the other, a stick-support located beneath the cutter and recessed to receive the rounded stick, and gages located on opposite sides of the axis of the cutter and adj ustable in respect thereto, said gages being likewise recessed to receive the stick and serving as stops for a shoulder on said stick, all substantially as specified.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.

JOHN ROSE.
